THIS MAKES YOUR USERS SAD

DO YOU SHARE OUR VISION?

We believe, that everybody should become a better professional and achieve the very best we can. Every day, at every project, with every mobile app.Amazing people support our vision — our first users, opinion leaders, friends and advisers. We are making Flawless App together with them:

Alex Shelpuk was involved in many our user interviews. He suggested several tech solutions for the current version of Flawless App. Alex works as a Head of Software in famous pet startup, Petcube.

Pipedrive founder, Ragnar Sass kicks our asses all the time. He motivates us to move faster and work smarter. And, we founded Flawless at his hackathon, Garage 48.

Sergey Lem is the fastest bug reporter ever. He tested our builds 5 minutes after we sent it! Thanks to Sergey Flawless App is so polished now :)

Sergii Zhuk is senior Android developer, our friend & advisor. We talked with him about Flawless even before Flawless App was done. Sergii always helps us!

You probably have heard Vixentael security talks. Anastasiia Voitova is a lead engineer, mission-driven speaker and red-hair Swift magician. She made for us 2.5h lecture on designer/developer workflow and how to fit Flawless App in it.

Andrey Skrupnic is a Head of Software in hardware startup, Concepter. He pushed us to launch paid product faster! It’s very inspiring advice from one of the first alpha users.

We met with Alexsander Akers during our Berlin trip. He gave us very useful insights on iOS development workflow in big product companies. Alexsander proposed ideas on integrating our product into that workflow.

Hector Zarate showed us how designers and developers can smoothly work together, even on such complex modular apps, like Spotify. Also, he kindly explained the concept of design language in dev environment.

Ignacio Romero is iOS developer in our beloved Slack. Thanks to Ignacio we fixed the signing issue. New users will no longer see the warning message: “this app is from an unidentified developer...”

HOW FLAWLESS APP WORKS

Select Design File

Simply choose a design from the interface, or drag & drop files onto the Flawless App icon in the menu bar. You can select one or multiple designs in different formats: sketch, jpeg, png, tiff or gif.

Choose Comparison Mode

Once a design file has been chosen, it will appear on your iOS simulator. You can use overlay or split comparison mode for spotting any visual differences between expected design and implementation. Flawless App supports comparison of portrait and landscape screens, so you can check pixel by pixel the quality of every design.

Inspect visual bugs in iOS simulator

Flawless App is integrated right inside your iOS simulator as a plugin. It allows to fix visual issues on the fly, before they cost you time and money.

No need to distract your development workflow by adding any third-party library. Flawless App works out of the box, without any additional setup.

OUR WONDERFUL USERS

They are happy with Flawless App and you will be too!

Misha Karpenko

Senior Software Engineer @ Microsoft

This simple app is indispensable in a UI perfectionist's toolkit. If you've polished a look of an iOS app at least once, you will notice an instant productivity increase. Screen rulers and design specs can get you far enough, but nothing beats the precision of a 1-1 pixel comparison. And Flawless is the easiest way to make it happen.

Peter Witham

iOS developer & designer

Flawless App helps me to figure out how close is my final app to initial design and it limits the visual bugs, if they appeared. And the team behind Flawless is awesome! I always got warm and welcoming support and that’s a high bar for pretty young startup team!

Sergey Butenko

iOS Engineer @MacPaw, ex-@Yalantis

We pay close attention to the design at Yalantis. Flawless App helps us to implement very complicated designs accurately comparable to the initial layouts. The most important is that pixel-perfect became an achievable norm now.
